` To aZZ whom it may concern:

Be it known that I, JOSEF ScHULHoE, of thel ing countries, to wit: inGreat Britain July 12, 1886, No. 9,066; in Austria-Hungary July 13,1886, No. 4,336/33,443; in France October 5, 1886, No. 478,875; inBelgium October 30, 1886, No. 74,923, in Italy November 12, 1886, No.'8,414; in Spain February 16, 1887, No. 10,452, and in Germany May 5,1887, No. 38,884,) of which I declare the following to be aspecification.

This invention relates to improvements in magazine-guns, and has specialreference to that class ofre-arms in which a sliding breech*- piece orbolt is employed, and wherein the magazine is arranged between the twoparts of the stock in immediate connection with the cartridge-chamber inthe breech-receiver.

The magazine, which has the form of a drum, is attached to the stock andbreech receiver or case underneath the latter, which is in this caseprovided with a corresponding opening in the bottom to permit theraising of the cartridges from the magazine into the breech receiver orcase. This magazine-drum is made to contain from eight to fourteencartridges, and is, parallel with its axis, provided with an interiorcentral arbor or small drum, around and parallel to which the cartridgesare arranged. This interior arbor turns in borings, and is rotated inone direction by the unwinding of a small chain arranged at the one end,the other end of which said chain is attached to the lid of themagazine. Thus when said lid is opened the central arbor of .themagazine receives one turn in one direction, when, as the door or lid isfully opened, said arbor is stopped by a spring-pawl catching into acorresponding notch in its end. The other end of this arbor is providedwith a spiral spring, which is tightened or wound when the magazine dooror lid is opened and the arbor rotated in one direction. By the actionof thebeforementioned pawl preventing the turning back of the arbor thespiral spring is also kept wound until the magazine-door is closed, whena pin, attached to the latter, strikes the pawl, thereby releasing thearbor, which is now turned back into its original position. This turningback causes the feeding of the cartridges into the chamber in the breechcase or receiver in the following manner: On its surface, parallel toits axis, the arbor carries aslightly-oscillating lever, which, when themagazine-door is open, stands in its highest position to the rightagainst the lower side of the case. The cartridges having been throwninto the magazine and the door closed, the spiral spring, acting uponthe arbor, forces it to turn, whereby said oscillating lever presseslaterally against the last cartridge, pushing them all before it, sothat one cartridge after the other is passed up an incline, with whichthe magazine is provided, into the breech-receiver case,where they arestruck by the sliding breech piece or bolt, pushed home into thecartridgechamber, and subsequently iired.

When the gun is to be used as a single loader while the magazine isfilled, a slide is pushed into the magazine, which passes over thecartridges and prevents them from passing out.

Fig. 4 is a rear view of the magazine with closedflap. Fig. 5 is a horizontal section of the magazine. Fig. 6 is a topview of the same. Fig. 7 isa front view of the closed magazine. Fig. 6lis a view ofthe cartridge-transport lever. Fig. 8 is a vertical sectionof the closed -magazine.

Like letters denote like parts in all the iignres.

The magazine of my improved gun is, as aforementioned, arranged betweenthe two halves of the shaft, and consists of a drum or casing, g,preferably1 of thin sheet metal,which is attached to the forward andrear halves of the shaft by means of the lugs p2, Figs. 2, 4, and 5, andp', Figs. 6 and 7, and appropriate screws. A stud or projection, gs, ofthe magazine fits into a suitable recess ofthe breech-receiver d, so asto fix thev magazine to the said breechreceiver. The upper part of thedrum gis cut away in order to allow a cartridge to pass through thesame, the drum being provided with an incline, g5, to enable the readyentrance of the cartridgeinto the breech-receiver, Fig.8. The innerwalls of the drum are provided with spiral surfaces m m, the object ofwhich will be fully described later on in this specification. A seconddrum or shaft, h, is arranged within and concentric to the walls ofthe'drum' g, and has its bearings in the end walls of the same. Theshaft h is at its rear end provided with a journal, h2, Figs. 3 and 4,to which the chain h5 is attached. The other end of this chain h5 isattached to the flap g* of the magazine, as shown in Figs. 3 and 4. Theforward end of the shaft or axis h is provided with ajournal, i, aroundwhich an appropriate spring, i2, is coiled. This spring '2 is attachedto the journal i of the shaft 7L by pins or screws i5 i6, and to thefront end of the drum lf/,by means of the pin, peg,or screw t3,in suchmanner that when the shaft h is rotated the spring will be put undertension. This movement of the shaft h is caused by the opening of theiiap y, as follows: The chain h5, which connects the flap g4 of the drumg with the shaft h, runs over a guide pin or roller, h, Figs. 3 and 4,and is coiled on the journal of the shaft when the drum is closed. Thisend of the shaft h is provided with an eccentric-disk or offset-wheel,it, in which a pawl, h3, gears when the ap g4 is opened, which said pawlis held in gear with the said disk by means of the spring h4 when theflap is opened. When the iiap is closed, the disk or wheel takes up theposition shown in Fig. 4, so that when the flap is opened the chain h5will cause the shaft h to make almost one revolution before the pawlcomes in gear with the tooth or offset of the disk or wheel, so that theshaft h is held in the position shown in Fig. 3 until the flap g4 isagain closed. In closing the said iiap g*- the pin g5 comes in contactwith the lever-pawl h3, so that the same is brought out of gear with theoffset or tooth of the disk or wheel '54, the chain lays itself looselyagainst the wheel until the disk or wheel is freed, and is wound on theshaft by the force of the spring 2, which was put under tension when theshaft h was rotated in opening the flap g4. The so -calledcartridge-transporter7 on the shaft h, Figs. 5, 6, Gf", and- 8, consistsof an oscillating lever, q, on the pivot or screw q2 g3, the movement ofwhich is limited by the length of a slot, i, in which a stud, qe, moves.A spring, q', arranged laterally on the transport-lever q, bears againstthe shaft h and retains the lever parallel to the said shaft.

The operation of the magazine is as follows: In order to fill themagazine the flap g4 is opened and puts the spring 112 under tension,

as aforementioned. The pawl h3 falls at i* onto d and thetransport-lever stands in the position shown in Fig. 8, near theopening. The cartridges are now loosely inserted in the magazine androll around the shaft l1., when the weapon is held to the one sideunt-il the first cartridge comes in contact with the incline g5 at theopening or cavity in the breech-receiver, Fig. 8. The magazine is nowfilled and the door g4 closed, the pin g5 releasing the pawl h3 andgiving the shaft h free motion. The spring i, having been put undertension by the rotary movement of the shaft 7L, has the tendency toreturn to its original position. The transportlever q presses againstthe last cartridge, so that the cartridges are pressed forward until theforemost cartridge ispressed up onto the incline g5, and when thesliding breech-piece is drawn back through the opening in thebreech-receiver into the cartridge-chamber in the same. In closing thebreech the sliding breech-piece a comes againstthe flange of thecartridge and pushes the said cartridge up the incline o, Figs. 5 and 7,into the cartridge-chamber in the barrel. When the last cartridge hasreached the incline g5, the transport-lever q is in the position shownby the dotted lines in Fig. 8, and the spring if is released fromtension.

It will be evident that .the operation of the parts will remain the samewhether one or more cartridges are laid in the magazine. If onecartridge islaid in the magazine,the shaft h, and consequently thetransport-lever g,will be moved in proportion, so that this cartridge isalso brought under the opening or cavity in the breech-receiver.v Vhenthe magazine is full, the closed breech-piece will prevent a cartridgefrom rising through said opening or cavity in the breech-receiver,whereas each time the breech-piece is drawn back a cartridge will risesufficiently, so as to be able to force the same into thecartridge-chamber in the barrel. The Hap g4, which is hinged atg to themagazine, is held in closed position by means of a suitablespring-catch. When the sliding breech-piece is drawn back, the flange ofthe cartridge-shell will strike against apin, r, fixed to the drum g,and extending through a cavity, r', in the breechreceiver d, so that thesame is ejected.

In order to be able to employ my improved weapon as single loader withfilled magazine, I employa slide, j, which, when not in use, occupiesthe position represented in Figs. 3, 4, 7, and 8. If the said slide j ispushed forward by means of the knob j', the same will occupy theposition, as shown by the dotted lines in Fig. 6, over the cavity oropening of the breech-receiver, and consequently over the opening in thedrum and above the cartridges in the same, thus preventing the saidcartridges from leaving the magazine. The sliding breech-piece will nowglide freely over the ICO IIO

cartridges in the magazine, so that the weapon can be used as singleloader until the slide 7' is withdrawn.when the magazine again cornesinto action. As the magazine is not located immediately beneaththeopening or cavity in the breech-receiver, but a trifie to the rear ofthe same, the inner walls of the drum g are pro vided with spiralguides,so that the cartridges, which originally lay somewhat to the rearof the said opening or cavity in the breech-receiver, will on their wayupward be gradually pushed forward until the uppermost cai`- tridgecornes in line with the said opening. A rib, n, applied to the innerwall of the magazine, serves to hold the cartridge in horizontalposition.

rIhe magazine can be readily emptied by simply opening the flap g4 andallowing the cartridges 4to roll out. If desired, the walls of themagazine can be perforated at g2 in order to be able to ascertainwhether the magazine is filled or not without having to open the ilap.

Having now particularly described and ascertained the nature of my saidinvention, and in what manner the same-is to be performed, I declarethat what I claim is- 1. In a magazine fire-arm, the combination,

I with the stock, barrel, and sliding breechpiece, of a magazine locatedbeneath the breechreceiver, and consisting of a drum or casing, g,having a cartridge-receiving opening therein and a hinged flap closingSaid opening, a rotary shaft, 7a, arranged concentrically within saiddrum g and havingjournal-bearing within the end walls thereof, a chain,h5, connected at its ends,respectively,to the rear of the shaft 7L andto the flap g4, and a spring, il, connecting, respectively, the frontend of said shaft li and the front end of the magazine gun,substantially as and for the purpose set forth.
